1、添加spring相关jar包

2、配置ehcache jar包。

3、添加ehcache mybatis 适配器jar包（在mybatis官网）

4、添加spring mybatis 适配器jar包（在mybatis）官网

5、pom.xml

6、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"
  xmlns:tx="http://www.springframework.org/schema/tx"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

  <!-- Spring希望管理所有的业务逻辑组件，等。。。 -->
  <context:component-scan base-package="com.atguigu.mybatis">
    <context:exclude-filter type="annotation"
      expression="org.springframework.stereotype.Controller" />
  </context:component-scan>

  <!-- 引入数据库的配置文件 -->
  <context:property-placeholder location="classpath:dbconfig.properties" />
  <!-- Spring用来控制业务逻辑。数据源、事务控制、aop -->
  <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="jdbcUrl" value="${jdbc.url}"></property>
    <property name="driverClass" value="${jdbc.driver}"></property>
    <property name="user" value="${jdbc.username}"></property>
    <property name="password" value="${jdbc.password}"></property>
  </bean>
  <!-- spring事务管理 -->
  <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
  </bean>

  <!-- 开启基于注解的事务 -->
  <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>
  
  <!-- 
  整合mybatis 
    目的：1、spring管理所有组件。mapper的实现类。
        service==>Dao  @Autowired:自动注入mapper；
      2、spring用来管理事务，spring声明式事务
  -->
  <!--创建出SqlSessionFactory对象 -->
  <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <!-- configLocation指定全局配置文件的位置 -->
    <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    <!--mapperLocations: 指定mapper文件的位置-->
    <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property>
  </bean>
  
  <!--配置一个可以进行批量执行的sqlSession -->
  <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactoryBean"></constructor-arg>
    <constructor-arg name="executorType" value="BATCH"></constructor-arg>
  </bean>
  
  <!-- 扫描所有的mapper接口的实现，让这些mapper能够自动注入；
  base-package：指定mapper接口的包名
   -->
  <mybatis-spring:scan base-package="com.atguigu.mybatis.dao"/>
  <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.atguigu.mybatis.dao"></property>
  </bean> -->
  
</beans>

7、mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
 PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
  <settings>
    <setting name="mapUnderscoreToCamelCase" value="true" />
    <setting name="jdbcTypeForNull" value="NULL" />

    <!--显式的指定每个我们需要更改的配置的值，即使他是默认的。防止版本更新带来的问题 -->
    <setting name="cacheEnabled" value="true" />
    <setting name="lazyLoadingEnabled" value="true" />
    <setting name="aggressiveLazyLoading" value="false" />
  </settings>

  <databaseIdProvider type="DB_VENDOR">
    <property name="MySQL" value="mysql" />
    <property name="Oracle" value="oracle" />
    <property name="SQL Server" value="sqlserver" />
  </databaseIdProvider>

</configuration>

注意：此处mybatis配置文件中没有配置数据源，数据源由spring负责。

此外还需要ehcache.xml配置文件,Mapper.xml文件。
